Glyphidocera cenae , new species

(Figs. 108–110, 323, Map 20 )

Diagnosis.— Relationships between Glyphidocera cenae and its congeners are difficult to determine because of the unique combination of features possessed by the former that include male abdomen absent of sex scales in male, a valva with a long falcate costal furca, and vesica of aedeagus with an apical cornutus with a bulbous base.

Description.— Head: Vertex and frontoclypeus with scales brown tipped with pale brown; labial palpus with outer surface brown intermixed with few brown scales tipped with pale­brown, and pale­brown scales; inner surface as above, except paler; scape of antenna brown intermixed with brown scales tipped with white and pale­brown scales, flagellum with alternating bands of brown and pale­brown scales; male 4th flagellomere not protuberant, 5th and 6th flagellomeres slightly excavated; proboscis with brown scales tipped with pale brown.

Thorax: Tegula and mesonotum with brown scales tipped with pale brown. Legs brown intermixed with few pale­brown scales. Forewing (Fig. 323): Length 9.0 mm (n = 1), with brown scales tipped with pale brown; cell with 2 faint brown spots, 1 near middle, 1 near distal end. Undersurface brown. Hindwing: Brown.

Abdomen (Fig. 108): Male with sex scales absent.

Male Genitalia (Figs. 109–110): Uncus elongate, broadly constricted near ½ length, apically rounded, apex narrowly rounded and setose; gnathos sparsely setose, protuberant, wide throughout length, apically upturned; tegumen slightly widened basally; dorsal strut of tegumen with arms convergent, fusing medially from posteroventral margin to base of uncus; valva with costa broadly downturned from a shallow depression slightly beyond a slanted, basal digitate process to apical furca; furca falcate, with a broad base; sacculus twisted apically, constricting valva near slightly before midlength, widening distoventrally, forming an elongate, broadly rounded cucullus; cucullus membranous and setose; vesica of aedeagus denticulate, bearing a conical cornutus with an abruptly dilated base; cornutus with one side shortened, exposing a hollow, basal cavity.

Female Genitalia: Unknown.

Distribution ( Map 20 ): Glyphidocera cenae is known from one collecting site in northcentral Costa Rica, inland from the Caribbean Sea near the border of Nicaragua.

Etymology: The species epithet cenae is derived from the Latin “cena,” meaning dinner.
